HDFC Bank — IMPS Transaction time out

I did the transaction of IMPS from hdfc bank to PNB bank on 1 April 2021
the transaction was timed out and amount debitted from hdfc bank and not creditted to pnb bank.

I called both banks, PNB rejected that amount not reached yet and HDFC side earlier they told to wait for 24 hours now Monday EOD that is 5 April 2021

This is IMPS transaction and 1 lakh amount is debitted and not refunded back yet

Please help to resolve the issue as early as possible
